(BANG) - Sienna Miller peeked at Heath Ledger's manhood while filming 'Casanova'.
The 'Layer Cake' star copped an eyeful of the hunky actor while they were shooting together in Venice.
Sienna - who is allegedly dating 'Star Wars' actor Hayden Christensen after splitting from on/off boyfriend Jude Law - also revealed Heath caught a glimpse of her naked.
She told Britain's Hotdog magazine: "We were in these rooms with a curtain separating us - as opposed to using our own trailers.
"The boys were farting next door and we were chucking food over each other. It was like being back at school - it was such a laugh.
"We saw each other's bits and bobs several times.'
